GRAVITY-FEED LUBRICATING SYSTEM.

Specification of Letters Patent.

Patented Mar. 9, 1915.

v Application filed August 19, 1914. Serial No. 857,462.

To all whom it may concern:

Be it known that we, FRANK A. SHOE- MAKER and WILLIAM E. ARCHER, citizens of the United States, residing at Norristown, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Gravity-Feed Lubricating Systems, of which the following is a specification.

This invention relates to lubrication and more specifically to a gravity-feed lubricating system.

The object of our invention is to provide a system of lubrication which will be simple in construction and effective in operation.

Our device designed to save oil, in that individual fetid regulators are provided to govern the flow of oil to each rubbing surface individually. All the conveying-pipes run from a common source of lubricant-supply which may be conveniently located at any place upon the machine above the points to be lubricated.

Other objects of this invention not at this time more particularly enumerated, will be clearly understood from the detailed description and drawings forming a part of this specification.

Furthermore, this invention consists in the novel arrangement and combination of parts more particularly described in the following specification and embodied in the claim appended hereunto and forming a part of this application.

Referring now to the drawings, which are merely illustrative of our invention, Figure 1 is a side elevation of our device illustrating its application to a fly-wheel, while Fig. 2 is an enlarged side elevation of the reservoir and feed control parts of the device. Fig. 3 is an end elevation of the same with the top shown in section. Fig. 4 is a fragmental longitudinal section of our device, while Fig. 5 is a fragmental cross-sectional view thereof enlarged taken on the line 55 of Fig. 2.

Referring further to the drawings wherein similar reference characters designate similar parts throughout the respective views 1 designates an oil reservoir, provided with a glass gage 2 on both sides thereof. A cover 3 is adapted to close the top of said reservoir, said cover being provided with an air hole 4 through the top thereof. A main feed pipe 5, regulated by a valve 6 connects said reservoir to the distributing device, above which said reservoir is mounted. Said distributing device consists of a casing :7 mounted on a bracket support 7 said casmg being provided with an opening 8 through which the main feed pipe 5 proects. The said pipe 5 is connected with a horizontally arranged auxiliary reservoir 9, mounted in casing 7 and provided with a plurality of downwardly projecting outlets 10. Said outlets 10 have mounted therein valves 11 adapted to regulate the flow of oil from each of said outlets. On the side of said casing 7 opposite said outlets 10 is mounted a plurality of conveying-pipes 12, provided with a funnel-shaped end 13 extending upwardly within said casing, adapted to receive the oil admitted through the outlets 10 and convey it by means of the pipes 12 to the fiy-wheel shaft 14 or any other part of a machine to which our system may be applied. In order to properly regulate the flow of oil from the outlets 10, glass windows 15 are mounted on both sides of the casing 7, opposite each of said outlets 10. By this means the operator can see just how fast the oil is flowing, and can regulate the valve accordingly.

The utility, adaptability, and advantages of our improved form of gravity-feed lubricating system being obvious, it is unnecessary to further enlarge upon the same herein.

Having now described and pointed out the new and useful features of our invention, we do not limit ourselves to the shape of certain parts where the shape is not es sential, nor do we restrict ourselves to the exact details of construction shown and described, but mean and intend to claim all equivalents and variations thereof not departing in principle from our invention and falling within the purview of the appended claim.

What we claim as our invention and desire to secure by Letters Patent is:

In a device of the kind described in combination, an oil retainer, a casing, said retainer mounted above said casing, a distributing tank mounted within said casing, a pipe leading from said retainer to said tank, a plurality of outlet pipes integral with said tank, means mounted upon said pipes whereby they may be opened and closed, a plurality of vertically disposed conveying-pipes o mounted through the bottom of said casing, In testimony whereof We affix our signaone end. of each of said conveying-pipes betures in presence of two witnesses,

ing placed opposite one of said outlet pipes FRANK A. SHOEMAKERJ adapted to receive oil admitted through said WILLIAM E. ARCHER;

outlet pipes, and said conveying-pipes Witnesses:
